Four men have been found guilty of the gang rape and killing of a young woman in Delhi last year.

A fifth suspect was found dead in his prison cell in March. His death is under investigation.

A sixth defendant, a teenager, was sentenced in August by a juvenile court to three years in a reformatory.

Since the trial began in early February, the specially convened fast-track court in New Delhi has heard testimony from 85 prosecution and 17 defense witnesses over 130 days.

Among those called to testify was the young man who was accompanying the victim and was also attacked. The court also heard from the victim’s mother and metropolitan magistrates, who recorded the statement of the victim from her hospital bed before she died.

All five defendants also testified, as did a female investigating officer and other police officials. The court also heard from DNA experts, doctors at the Delhi hospital where the victim was first admitted and clinicians from Singapore’s Mount Elizabeth hospital, where she was flown for treatment before she died of her injuries on Dec. 29.

The statements of defense witnesses, mainly the suspect’s family members, have been recorded in 75 pages. The court has recorded testimony from the suspects running to more than 400 pages. Read some excerpts from their testimony here.
